ABSTRACT Sanitary landfill is the most common approach of solid waste management used in many countries. However, the present landfill sites in most developing countries are already nearing their capacity due to the increasing population and tremendous urbanization growth that lead to the high generated of municipal solid waste (MSW). Landfill siting is a difficult and complex process requiring evaluation of many different criteria. A multicriteria decision making technique, Analytical Hierarchy Process (AHP), which utilizes a multi-level hierarchy structure consist of objective, criteria, subcriteria, and alternatives is applied in this study. This paper presents the development of the AHP model in selection of an appropriate landfill site in Kuantan, Pahang. The input from the experts has been used to determine the evaluation criteria. Eleven criteria has been selected and classified into four main categories, which are hydrological/hydrogeological factor, morphologic, social criteria and economic impact. Three potential landfill sites had been identified as alternatives, which are Sungai Karang, Tanjung Lumpur and Beserah. As the result, Beserah had been ranked as the first alternatives with highest composite priorities values (0.383), followed by Tanjung Lumpur (0.360) and Sungai Karang (0.266).
